Bicycle Stems and Risers

Long/short, angled/straight - the right combination of bicycle stems and risers will give you the comfort of proper body positioning.

Bicycle stems and risers play a pivotal role in how a bike fits the rider and how it handles when on the road, trail or track.  Their basic function is to ensure the handlebars are securely clamped to the fork steerer and at the correct height. The stem type, materials and dimensions along with the riser height are important so choose carefully. The majority of bikers choose a threadless stem for their MTB which bolts directly onto the fork's steerer tube.  The plug-in quill design is generally found on the older bikes.  Aluminum alloy is by far the most common stem material. Carbon fiber models are lightweight and found at the top end of the bicycle market.  Stems are available to fit a range of steerer tube sizes with 1 1/8" being the most common on MTB and road bikes.  1" and 1.5" sizes may be required for you bike. The clamp has a range of sizes as well to fit different handlebar diameters. The 25.4mm standard size or the 31.8mm oversize are found on the MTB bikes of today.  The later is now actually the most common owing to its properties of strength and stiffness.  Length is critical here. Road riders tend to prefer a stem length based on the overall bike fit and positioning.  For off-road riders, the length of the stem is critical in determining how the bike handles.  Shorter stems result in quicker and more responsive handling that is a definite advantage on technical singletrack ridding.  Many riders find a mid-length of 60 - 80mm provides the perfect balance of responsive steering and pedal-efficient positioning.  Rise refers to the stem's angle in degrees relative to the fork steerer tube.  It will affect the bike's positioning and reach.  A 'zero rise' is essentially straight.  A stem with a rise of 10 has a 10 degree angle between steerer and handlebar clamp areas. So, whatever style of bike you have and the type of riding you do, the bicycle stems and risers combination will give you a fine-tuned experience.EquipBike.com will send them to you with free shipping.
